smartctl --scan -d megaraid

Before querying the drives, you must find out how the controller identifies each physical drive. smartctl includes a native scanning utility that detects hidden arrays. Run the following command with root or sudo privileges: sudo smartctl --scan Use code with caution.

If you are working with SSDs behind a PERC controller, a more precise command that often works better for SATA-to-SAS translation is: smartctl -a -d sat+megaraid,N /dev/sda Use code with caution. smartctl --scan -d megaraid Before querying the drives,

: Even if you have multiple physical drives, you usually use the same logical handle (e.g., ) for all of them; the part is what differentiates the physical disks. MegaCli commands to check for specific media or predictive failure errors? Check for Megaraid (and other Physical disk/raid) problems
